No, of course they all have a charge controller, you need that with lithium batteries. However it will always keep the battery topped up, which does put significant strain on it over time. I have heard about devices that got destroyed within only months of being kept on a charger 24/7.

You can keep using the current version without renewing your license, so there is no rush

Be very careful about leaving a phone or tablet on a charger for an extended period of time. The vast majority do not support bypass charging for preserving the battery. That means your battery may fail catastrophically after only a few weeks or months of constant charging.

Closing in on 4000 hours in Rocket League over the past 10 years. It can be terribly frustrating at times because bad actors have been undermining the matchmaking system for years. Still there is nothing that compares to the flow and possibility for skill expression in Rocket League, so I always come back to it.
